Below in conjunction with specific embodiment, being illustrated content to the process of prediction bandwidth of air-interface shown in FIG. 1 can be with It is as follows:
Step 101, it when data service starts, first eats dishes without rice or wine theoretical bandwidth and preset bandwidth according to terminal is current Distribution coefficient determines the prediction available bandwidth in the period 1 of terminal.
Wherein, theoretical bandwidth of eating dishes without rice or wine can be the terminal in the influence for not considering other terminals to bandwidth, being connected with base station When only this terminal carries out data service, the maximum bandwidth value that terminal can be assigned to, the value is only currently located channel with terminal Signal quality it is related.Bandwidth allocation coefficient can be allocated to the proportionality coefficient of the bandwidth and theoretical bandwidth of eating dishes without rice or wine of terminal.
In an implementation, the communication link of terminal to server is divided into two sections based on the air interface of wireless network, first Section is wire link part of the server to base station, and second segment is radio link portion of the base station to terminal, it may also be said to terminal Communication link is established by base station and server.After base station access by terminal, base station can be terminal distribution bandwidth of air-interface, if Terminal does not generate data service, and base station is terminal distribution minimum access bandwidth, if terminal, there are data service, base station if can base The actual bandwidth situation of channel where terminal is the corresponding bandwidth of terminal distribution.In order to guarantee the utilization rate of bandwidth of air-interface, need The actual bandwidth to make base station distribute to each terminal as far as possible is utilized to the greatest extent, i.e. transmission industry of the server to terminal The bandwidth that the rate (can be referred to as packet sending speed) of business data packet should distribute to terminal with base station is essentially identical.To terminal It, can with the cyclic forecast prediction that terminal is likely to be obtained within next a period of time during carrying out data service With bandwidth, available bandwidth Tell server can will be predicted later, and then server can determine hair according to prediction available bandwidth Packet rate.Specifically, when data service starts, terminal can obtain the first of present channel from base station and eat dishes without rice or wine theoretical band Then width eats dishes without rice or wine theoretical bandwidth and preset bandwidth allocation coefficient according to first, determines that prediction of the terminal in the period 1 can Use bandwidth.Wherein, preset bandwidth allocation coefficient can be the technical staff of base station previously according to network type and other factors, Empirically algorithm is calculated, and is then sent to terminal, so that terminal stores it in local.In order to ensure in number of terminals The utilization efficiency of bandwidth of air-interface when starting according to business, preset bandwidth allocation coefficient can be set between one (0,1) one A the larger value, thus server can in most cases by more than or equal to terminal actual available bandwidth packet sending speed into Row is given out a contract for a project.Data service starts to refer to that the data service initial launching stage of terminal may also mean that data service from interruption The stage restored under state.In addition, the period (duration of starting point and a cycle including the period) herein can be terminal After data service starts, terminal is negotiated with server, can also at the beginning of the starting point in period can be data service Any one time point after being started with data service.
Optionally, the processing of the prediction available bandwidth of above-mentioned determining period 1 can be such that by terminal it is current first The product of theoretical bandwidth of eating dishes without rice or wine and preset bandwidth allocation coefficient, the prediction in the period 1 for being determined as terminal can use band It is wide.
In an implementation, the first theoretical bandwidth of eating dishes without rice or wine of terminal detection is the influence for not considering other users to bandwidth, is only examined Consider under current signal quality, the maximum bandwidth of air-interface that terminal can obtain, and bandwidth allocation coefficient is in the channel in the presence of more In the case where terminal, the bandwidth that present terminal can be assigned to accounts for the ratio of total bandwidth, therefore, can be empty by terminal currently first Mouth theoretical bandwidth and the product of preset bandwidth allocation coefficient are determined as prediction available bandwidth of the terminal in the period 1.

In an implementation, which can be used band after the prediction available bandwidth in the period 1 has been determined by terminal Width is sent to base station, and after the prediction available bandwidth for receiving terminal transmission, can send prediction to server can use band for base station Wide and terminal network address mark, network address mark can be IP address herein, so that server can be at first week The interim rate that business data packet is sent according to the true directional terminals of prediction available bandwidth, and then can be according to the rate to above-mentioned net Network address identifies corresponding port and sends business data packet.
Step 103, whenever reaching predetermined period time point, the practical business of the terminal in the period currently terminated is detected Bandwidth, it is current according to bandwidth allocation coefficient adjusted and institute's terminal according to practical business Bandwidth adjustment bandwidth allocation coefficient Second eat dishes without rice or wine theoretical bandwidth, determine prediction available bandwidth of the terminal in next period, prediction available bandwidth be sent to clothes Business device, so that server sends business data packet according to prediction available bandwidth in next period.
In an implementation, in each period when carrying out data service, server can according to stable packet sending speed to Terminal sends business data packet, while base station can adjust distribution according to the network condition of channel where current time terminal in real time To the actual available bandwidth of terminal.In this way, terminal can detecte the period currently terminated whenever reaching predetermined period time point The total business data volume that interior terminal receives, is then currently terminated total business data volume divided by cycle duration Period in terminal practical business bandwidth.Terminal can be according to the above-mentioned bandwidth of practical business Bandwidth adjustment detected point later Distribution coefficient, further, the signal quality of channel, that is, detect current second where terminal can also detect current time terminal It eats dishes without rice or wine theoretical bandwidth, second eats dishes without rice or wine theoretical bandwidth and the first theoretical bandwidth of eating dishes without rice or wine may be the same or different, and then terminal can To determine that terminal can in the prediction in next period according to bandwidth allocation coefficient adjusted and the second theoretical bandwidth of eating dishes without rice or wine of detection With bandwidth, then the prediction available bandwidth can be sent to server by base station by terminal, so that server is receiving this After predicting available bandwidth, business data packet is sent to terminal according to the prediction available bandwidth in next period.
Optionally, according to the calculation of the prediction available bandwidth in the above-mentioned period 1, relevant treatment can in step 103 With as follows: by the second current product for eating dishes without rice or wine theoretical bandwidth of bandwidth allocation coefficient adjusted and institute's terminal, being determined as terminal Prediction available bandwidth in next period.
In an implementation, terminal is eated dishes without rice or wine after theoretical bandwidth having adjusted bandwidth allocation coefficient and detected current second, can Second the eat dishes without rice or wine theoretical bandwidth current with money distribution coefficient and terminal adjusted to be multiplied, product is then determined as terminal Prediction available bandwidth in next period.
Optionally, depending on the difference of practical business bandwidth, the mode for adjusting bandwidth allocation coefficient is also different therewith, correspondingly, Relevant treatment in step 103 can be such that if practical business bandwidth is less than prediction available bandwidth and default accelerator coefficient Bandwidth allocation coefficient adjustment is then the second ratio for eating dishes without rice or wine theoretical bandwidth for predicting that available bandwidth and terminal are current by product；Such as Fruit border service bandwidth be greater than or equal to prediction available bandwidth and default accelerator coefficient product, then calculate prediction available bandwidth with The second current ratio for eating dishes without rice or wine theoretical bandwidth of terminal, and be ratio by bandwidth allocation coefficient adjustment and default accelerated factor multiplies Product.
Wherein, default accelerator coefficient can be technical staff rule of thumb formula be calculated, for judging server The ratio of the practical business bandwidth and prediction available bandwidth that whether need to accelerate to give out a contract for a project, the practical value for presetting accelerator coefficient can It adjusts, between 0 and 1.Default accelerated factor, which can be, is wider than prediction available bandwidth in the practical business band for judging terminal Afterwards, acceleration degree when server sends business data packet to terminal, the practical value for presetting accelerated factor can be according to network Type and other factors are adjusted, and value is greater than 1, less than the ratio of eat dishes without rice or wine theoretical bandwidth and practical business bandwidth.
